Help with configuration AIO

[DrJohnM61]

Hi, I have a gen 1 AIO and gateway. I have also have been successfully using historic versions of GIVTCP installed and just upgraded to V3.0.4 after some complications.

There are two inverters shown. 1) the gateway and 2) the AIO battery.

Should I have both these enabled or just the AIO?

Or should both be configured but the AIO just report the battery status?

Also...

The GIVTCP dashboard only shows the AIO inverter but is also showing what looks to be an error code:

Inverter (GivTCP2)
Solar Power 0.00 kW
Target Charge 100%
Batteries 45%
Status Discharging 0.53 kW
undefined% NaN kWh

Is that due to a configuration issue?

Thanks for help on this in advance.
